8 Analog Input Channels:Provides 8 independent analog input (AI) channels, ideal for acquiring continuous voltage and current signals in medium-scale process control applications.
High Accuracy and Resolution:Offers 12-bit effective resolution (excluding sign bit), enabling precise analog signal measurement and stable process data acquisition.
Programmable Input Filtering:Supports configurable input filters (fast, standard, slow response) via STEP 7 software—effectively suppressing noise and signal fluctuations from the field.
Group-Based Electrical Isolation:The 8 input channels are divided into two groups of 4 channels each, with galvanic isolation between groups, preventing ground loops and cross-talk interference.
Wire Break Detection (for Current Inputs Only):When using 0–20 mA or 4–20 mA inputs, the module can detect open circuits (sensor disconnection) and report faults via diagnostic data—enhancing system reliability.
